                       STERICYCLE OBTAINS NEW $400 MILLION
                        SENIOR UNSECURED CREDIT FACILITY

Lake Forest, Illinois, July 5, 2005 - Stericycle, Inc. (NASDAQ: SRCL) today
announced that it has obtained a new $400 million senior unsecured revolving
credit facility from a group of lenders led by Bank of America, N.A., as
administrative agent, JPMorgan Chase Bank, N.A., as syndication agent, and
Fortis Capital Corp. and Calyon New York Branch, as co-documentation agents. The
new credit facility has a five-year term, maturing in June 2010.

The new credit facility replaces Stericycle's existing senior secured credit
facility, consisting of a $205 million revolving credit facility (under which
borrowings of $136.5 million were outstanding) and a $62.4 million Term A loan,
both maturing in September 2007. Under the new credit facility, the current
effective interest rate on Stericycle's borrowings will be reduced from 1.25% to
0.75% over LIBOR on LIBOR rate borrowings and will remain unchanged at the prime
rate on base rate borrowings.

The new credit facility will result in a one time pre-tax charge in the quarter
ending June 30, 2005 of approximately $0.2 million, representing the write-off
of unamortized fees relating to the prior credit facility. In connection with
the new credit facility, Stericycle paid fees of approximately $1.2 million,
which will be amortized over the five-year term of the facility. The write-off
of unamortized fees in the quarter ending June 30, 2005, and the future benefits
resulting from lower interest rates under the new credit facility, partially
offset by the amortization of the fees in connection with the new facility, have
not been reflected in the earnings guidance that Stericycle has previously
given.
